I was looking for a way to extend my lens collection about footed pajamas and came up with the idea of making a lens about onesies. Why? Onesies and footed pajamas are very similar. If you have a baby, in the winter you will dress them in footies and in the summer in onesies. But doing this lens, I learned a few things.
First, I had never heard about onesie extenders. What a great way to get more life from your baby's onesie.
Second, I learned that there are onesies for adults which snap at the crotch. These are mostly used by adults who use diapers, due to incontinence or other reasons.
Small things, but it seems like whenever I make a lens, I learn something in the process.
